To clarify, I saw these problems with Gmond not gmeta. On my stock
RH8.0 gmeta seems to work fine. Gmond's metric-gathering threads die,
and I see only CLUSTER and GANGLIA_XML tags, but no METRICs.
However, if I let the service go on long enough, some metrics get
through occasionally. They end up having TN (age) values of 200k or so
typically.

There seems to be no problem with the arguments to debug_msg(); both
are valid strings.
I get the same behaviour with a gmetad compiled from CVS HEAD.
I'm running a pretty stock Red Hat 8.0, with gcc 3.2 and glibc 2.2.93.
